"Here, and here. Let Qin Qiong and Cheng Yanjin capture it as soon as possible, and then concentrate all their efforts on blocking the road to the Western Turks in these two counties for me. Li Wenyuan nodded to the Momo County and Shanshan County on the map and said to the military commander on the side.

Seeing that the military commander in front of him went out, Li Wenyuan stretched out his hand and beckoned a quartermaster officer and said: "Order Zhang Juntai's army to advance to Dunhuang County, and the Wudelu army to go and cooperate with Qin Qiong's army to attack the two counties." ”

"Then order the new city lord to make proper arrangements for the livelihood of the people under his rule within seven days, resume production, and appease the people." Li Wenyuan said to the military commander next to him.

After several orders were given, Li Wenyuan sat behind Li Liang's desk, took a sip of the teacup on the table, and closed his eyes to recuperate. During this time, his hard work was also not light, and it was also a lot of pressure to defend the fortified city in the face of Li Liang, who was twice his own strength, and the materials consumed every day by the army were almost astronomical, and the pressure on his side was also not small.

But fortunately, he temporarily asked Zhang Juntai to get a yin soldier who pretended to be a ghost to borrow the way, which shocked Li Rail's army, and Li Rail even abandoned the city and fled, which made Guazhou City cleverly take it. However, Li Wenyuan was also a little worried in his heart, the ancients accepted new things very quickly, at least faster than he imagined, and the gunpowder he had in hand was estimated to not be kept secret for too long, and before that, he had to find a way to increase the lethality of his army equipment.

How can you increase the lethality of your army's weapons? He has now equipped his army with the strongest armor, even his own musket must be fired against the Mo Dao armor to shoot iron projectiles to shoot through, Li Wenyuan really can't think of any other weapon that can pierce this kind of heavy armor, but because of the high physical requirements of the soldiers, it can't be equipped on a large scale.

The explosion of the artillery test shot also gave Li Wenyuan a headache, he really needs a heavy weapon that can kill the enemy on a large scale, and it is best to use it for siege, at this time Li Wenyuan seemed to remember something, suddenly got up, rummaged through the official documents left by Li Liang, and finally found a page of paper, which read: There is a mountain in the south of Yanshou County, and the stone springs are water, which is as big as a basket, inedible, and the people of the county call it stone paint. It is called stone paint, but it can be burned in water, and there is a fire image in the upper runes.

That's right, this is it. Li Wenyuan took the paper in his hand and studied it carefully, and worked hard to read the records in his mind. In the end, I finally remembered the source of this sentence in the corner of my memory, and the first half of the sentence was a kind of product information recorded in the "Book of the Later Han" compiled by Fan Ye of the Jin Dynasty in the previous dynasty. It seems to be surface oil similar to the Greek fire, and it is easy to collect, but due to the backward production process, the combustion efficiency is not high.

I carefully searched in the official document, and finally found another page, which read: Today, this stone paint can be produced in Yumen County, Jiuquan County, burning smoke, smoke can be ink, born in the ground infinitely, not as pine sometimes exhausted.

Li Wenyuan found the craftsman who accompanied the army, this person is called Jin Sheng, the son of the gold shopkeeper, and he has won the true inheritance of the gold shopkeeper, and this time he also took the initiative to ask to follow the army to the west and build siege equipment for the army. Li Wenyuan found him and asked, "Do you know such a thing as stone paint?" Ling Zun mentioned it to you? ”

Jin Sheng frowned and thought for a while and said, "Stone paint? The manager wants to ask about kerose, right? ”

Li Wenyuan nodded hurriedly and asked, "Yes, it's the kind of fire oil that can burn in water, do you know this thing?" ”

Jin Sheng nodded and said: "My father mentioned that during the proclamation of Emperor Wu of Zhou, the Turks besieged Jiuquan, took this fat to light the fire, burned its attack tools, and saw that the water became clearer, and Jiuquan relied on it to get help. The fat mentioned here is a black ointment, which ignites when touched by fire and cannot be extinguished by water. ”

Li Wenyuan asked excitedly, "How did you ask you to collect and refine?" ”

"My father mentioned that he took fire oil from a clay pot, and then covered the mouth of the crockpot with cloth, and shaded it, and after a long time, it was anointed, and with strong wine, it burned when it caught fire." Jin Sheng thought for a while and said.

"Do you know how to find this oil?"

"Born in the sand and gravel of the water, mixed with the spring water, it comes out of confusion." Jin Sheng, who had already remembered these things, said without hesitation.

"God help me!" Li Wenyuan couldn't help but want to look up to the sky and howl, and first said to Jin Sheng: "Now I have Yumen County, Jiuquan County produces fire oil, you immediately go to find it, and set up the Fire Oil Department after finding it, you are the director of the General Administration, and you are in charge of all the fire oil production, especially pay attention to secrecy, as for the safety of the Fire Oil Department, the night owl is responsible for defense, you try to recruit as many craftsmen as possible to produce this kind of fire oil in large quantities, I am teaching you a refining method, and the fire oil extracted is more intense." Li Wenyuan said and picked up the pen and brushed the paper to write a little bit, all of which are purification methods for petroleum, which are common sense known to any person who has been exposed to chemistry in later generations, but at this time it is an extremely advanced process, and it is the experience accumulated for decades.

As a craftsman, he naturally knows how precious an improved recipe is, so at this time, he took the paper handed over by Li Wenyuan to record the refining method and hid it, and arched his hand to Li Wenyuan and said: "Don't worry, this trip will live up to the trust of the manager." ”

Li Wenyuan nodded and said, "Your father and son both serve under me, and I will definitely not treat you two badly in the future." Don't worry too much about it at this point, just do your job. ”

After getting the news of the oil oil, Li Wenyuan's train of thought was finally opened, since at this time he could not make the so-called cannon that eroded dozens of miles with one cannon, but he could find another way to imitate Greek fire for land warfare, but it was a pity that the people of Constantinople regarded this technology as a treasure, and the secrecy was extremely good, so good that after a hundred years, there was no one until the formula of this secret weapon. After the Greek fire-making process was lost, the only thing left to wait for the Kimburgers was to be blasted open by the Cannons of Urban.

But now, Li Wenyuan has a recipe that is cheaper and more efficient than Greek fire: Molotov cocktail.

This kind of magical thing is famous in the hearts of all military fans in later generations, and it is very easy to make, only need to put some mixed fuel into the bottle, plug the cloth at the mouth of the bottle, and throw the incendiary bottle after igniting the cloth, after the Molotov cocktail hits the hard object and shatters, the fuel inside will flow out, and the cloth strip contaminated with the fire at the mouth of the bottle can directly ignite the fire, and the water can not be extinguished, whether it is used for siege, defending the city, or field attack camp is a sharp weapon.
